From the foregoing it-Will be seen that the device forms a base of considerable area for the jack so that the jack will not sink into mud or other soft surfaces when in use and if the base, with the side members in their in- 95 ward position, is not sufficient to prevent this sinking of the jack, then the side members can be moved outwardly by loosening the thumb nuts and pulling the side members outw wardly until the bolts engage the inner ends 1%
